I have several of these storage boxes, in different sizes. They are sturdy and good looking. I buy my dry cat food in bulk and these keep everything nice and fresh because of the lids fitting so well. They also stack very nicely

I bought these to go with 2 existing ones and wanted to stick with the same type so I could stack them. They are very robust and so far none of them have split like cheaper alternatives. They are ideal for storing foolscap document wallets and large lever arch files. The only problem is trying to find them in store maybe because they are not a standard stock item or they are popular. I got fed up looking so did click and collect from ASDA and received them within a few days. I won’t consider buying other manufacturers’ products anymore.

These are great !. I am trying to organise my clutter and these are ideal. They are strong with handles which clip down onto the lids making the lids secure and the boxes easy to transport. Because they are transparent you can immediately see what you have stored in them without having to open them. The boxes are nice and strong and I see them lasting for years. I bought 4 of this size and they easily, and safely, stack on top of each other. I will definitely be buying some more.

These are the best storage boxes I've ever had and I have many.This size now holds my Halloween decorations.All safe and no longer in cardboard boxes - hopefully they are mouse proof.
Really Useful Boxes are excellent! The box I received though is the standard 21L variant, not the XL. The standard is pictured, and the dimensions provided on Asda's listing are for the standard, so I can't really grumble. Maybe a typo? Not what I was expecting, slightly smaller, but great all the same ;-)
Bought 10 of these to tidy garage. I only buy these boxes now, as I have tried many over the years and these are nice and strong and the clips do actually keep the lids on. Bought this size so that they are easy to manage because they are quite heavy. I also have the large and medium size for Christmas decorations they are great because they stack easily and protect my expensive decs.
I always use the really useful box co for storage. They are of a very sturdy material and the clip lids make sure contents remain safe. Very good for archiving paperwork, storage, toy boxes etc. So versatile. So many different sizes available. Yes they are expensive, but quality is worth it. We have archived paperwork in them in a garden shed for years.
Good solid high quality storage box. Using with 2 x 12 compartment inserts which fit perfectly meaning no cross-contamination if the box is tipped up or over.Best storage boxes available.
I needed to find a waterproof box that would fit under my sink in the bathroom. I wanted to store towels in there because I'm in an apartment with very limited storage and the space under the sink was unused valuable space. The trick was finding a box that fit within the space and filled that space as much as possible. This box did just that.
These are by far the best boxes I’ve ever brought and I have thrown away so many it’s false economy they are tough plastic with good handles on them and the fact they stack wonderful. One point off from them being called xl this could be a manufacturing name but these aren’t anywhere near the xl sizes the company actually does like 82 and 84 litre tubs so I was surprised how small they were when they first arrived but it ended up they fitted perfectly in the wardrobes so it all worked out. Wish Asda app would update measurements on things as litres means nothing. I’ve put this on their questionnaire feedback for years but they still don’t and it would make life easier as I’m having to swap between the website and the app which defeats the purpose of the app!I ... MoreThese are by far the best boxes I’ve ever brought and I have thrown away so many it’s false economy they are tough plastic with good handles on them and the fact they stack wonderful.
